DIE-CARRIER. N 0. 859,214. Specification of Letters Patent. Patented July 9, 1907.

Application filed July 14,1906. Serial No. 326,205.

To all whom it may concern:

Be it known that I, RICHARD Gninsnn, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have in I is shown as substantially rectangular in section, and the 55 cross section of the sockets 8 is similar, but of slightly the die into the socket. The die is also provided with a 1 of dies used in machines for prod ucing printing surfaces, ledge or projection 14 on the concave or inner side of its also known as reliefographs. In such construction, a number of dies are arranged in a cylindrical shape and upon the member being rotated to bring a desired one of the die ends adjacent a printing surface, such die is 1 deflected radially to engage such surface. In a United States Patent N 0. 582,178 granted to W. E. Crane, such a construction is shown, in which the several die members are integrally connected with the holder. By this means, it was practically impossible to remove one engage the shoulder portion and retain it in such position to prevent removal of the die. The stop portion 13 70 will prevent further insertion of the die and together with the ledge 12 will lock the die against endwise movement except upon the application of considerable force. To remove the die, strong tension tending to ber of slots 17 registering or in alinement with the said sockets 8. A disk portion 18 connects a cylindrical porduring the operation of bending each die when brought tion I9 with the hub, which cylindrical portion is proto the printing surface. At the same time each die the die from the socket. By such construction no oper- 3 5 ation of parts is necessary to mount the die in the holder In the accompanying drawing representing one embodiment of my invention, Figure l is a perspective Fig. 2 is a longitudinal section through the same. Fig. 3 is a view similar to Fig. 2 enlarged showing a portion only of the holder with the die inserted. Fig. 4 is a View similar to Fig. 3, with the die removed. Fig. 5 is a side elevation of the die member separate and Fig. 6

is a plan view of the same.

The die holder denoted generally by H is provided distance removed from the shoulder 12 to limit the in with a cylindrically arranged series of sockets denoted sertion of the die shank. ie members being resilient, pressure applied on The d the die member 9. This die member is preferably of the free end of the'die radially outward will cause the 105,

printing character, illustrated as in relief but which means of a plunger 23 as indicated in Fig. 2. By this I. evidently could also be intaglio. The shank of the die means upon rotation of the holder upon its axis, any dea shoulder portion, a plurality of resilient dies located in said sockets, the end portion of each die being bent from one side and provided with a ledge on the opposite side at the end whereby upon insertion of the dies in the sockets, the bent portion wilt cause the ledge to engage the shoulder portion of the socket and removably retain the dies in position.

A die member comprising a cylindrical holder having a series of longitudinal channels on its periphery, a band arranged on the cylinder above the channels to tform a socket portion for each channel, an annular groove adjacent the band to form a ledge at one end of each socket portion, a plurality of resilient die members of a width permitting insertion in the channels and socket portions, but of less thickness than the axial dimension ot the socket, each die member being bent from one side near the end and provided with a ledge on the opposite side at such end, whereby upon insertion of such end of the die into the channel and socket portion, said bent portion will be llexed lending to straighten ihe'die, and upon further movement of the die member, the ledge will be forced into engagement with the shoulder at said annular groove, removably retaining the die members in the holder.

sired die may be brought to register with the plunger 23, and thereupon reciprocation oi the plunger would cause the die to be lowered to engage a printing surface P indicated in Fig. 1. Upon release 'lrom the plunger the die at once returns to its normal position. It will be observed that the bending of the die member outwardly tends to force the ledge portion at its opposite end the more strongly into engagement with the shoulder portion, and cause a stronger retention of the die in its socket, instead ol bending to loosen the die or withdraw it. Whereas an application oi iorce endwise on the die member will cause it to disengage from the ledge and permit withdrawal.

Having thus described my invention, 1 claim:

1. A die member comprising a holder provided with a socket portion having a shoulder portion, and a resilient die member, the end portion oL' the die being bent iroin one side and provided with a let go on the oppositeside at the end whereby upon insertion of the die in the socket, the bent portion will cause the ledge to engage the shoulder portion oi? the socket and reniovably retain the die in the RIC HARD G RI ESER.
